Our growing portfolio of Battery Energy Storage Systems (BESS) supports energy security across national electricity networks and helps accelerate the global energy transition.
Learn about the different stages of development from origination to commissioning and final operations of a BESS project.
Once Development Approval (DA) is granted, the project enters the pre-construction phase. Final designs are completed, incorporating any conditions from the DA. Key contracts for construction, equipment supply, and grid connection are negotiated and awarded. These agreements provide the basis for securing project financing. After financial close is achieved- when all funding arrangements are finalised- the project is ready to proceed to construction.
This phase involves the physical delivery of the BESS, including site preparation, civil and electrical works, equipment installation, and grid connection. Strict attention is paid to safety, quality control, and construction timelines. Throughout this stage, the project team works closely with contractors and local stakeholders to ensure compliance and minimise disruption. This phase is complete once all systems are installed, tested, and the BESS is ready for commissioning.
Once construction and commissioning are complete, the BESS enters the operational phase. At this stage, the system begins storing and dispatching energy in response to grid demands or local energy needs. The BESS is continuously monitored using advanced software to ensure safe, efficient, and reliable performance. Routine maintenance and inspections are conducted throughout its lifespan to optimise operation and uphold safety standards. This milestone is achieved once the system is fully tested, energised, and actively contributing to the energy system.
At the end of the BESS's operational life, this phase involves safely dismantling and removing the equipment, restoring the site, and responsibly disposing and recycling of materials. Decommissioning is carried out in line with environmental and regulatory requirements to minimise environmental impact and return the site to a suitable condition for future use.
